5.0 g of brass (Cp = 0.38 J/g-oC, initially at 68oC) and 3.5 g of aluminum (Cp = 0.9 J/g-oC, initially at 83oC) are dropped into 20 g of water (Cp = 4.184 J/g-oC, initially at 23oC).Based on the described system, which of the following statements is/are correct? Check all that apply. The water will evaporate. For each material, the heat involved is sensible heat. The equilibrium temperature will be greater than 23oC but less than 83oC. The temperature of the brass will increase. The temperature of the aluminum will decrease.

Assuming no heat loss to sorroundings, we can balance the heats as follows: Q brass +QAI = QH20, ---…

Question

5.0 g of brass (Cp = 0.38 J/g-^oC, initially at 68^oC) and 3.5 g of aluminum (Cp = 0.9 J/g-^oC, initially at 83^oC) are dropped into 20 g of water (Cp = 4.184 J/g-^oC, initially at 23^oC).

Based on the described system, which of the following statements is/are correct? Check all that apply.

		The water will evaporate.
		For each material, the heat involved is sensible heat.
		The equilibrium temperature will be greater than 23^oC but less than 83^oC.
		The temperature of the brass will increase.
		The temperature of the aluminum will decrease.
